[PATCH] drm/doc: Add section in the introduction page about learning material

[Javier Martinez Canillas]

The Linux DRM subsystem supports complex graphics devices and it could be
quite overwhelming for newcomers to learn about the subsystem's internals.

There are lots of useful talks, slides and articles available that can be
used to get familiar with the needed concepts and ease the learning curve.

Add a section to the intro that contains these DRM introductory materials.

+Learning material
+=================
+
+Since the Linux DRM layer supports complex graphics devices, it can be quite
+overwhelming for newcomers to get familiar with all the needed concepts and
+learn the subsystem's internals.
+
+To shallow the learning curve, this section contains a list of presentations
+and documents that can be used to learn about DRM/KMS and graphics in general.
+
+The list is sorted in reverse chronological order, to keep the most up-to-date
+material at the top. But all of them contain useful information, and it can be
+valuable to go through older material to understand the rationale and context
+in which the recent changes to the DRM subsystem were made.
